High strength, low alloyed, zinc coated (galvanized) steels by continous hot-dip process for cold forming
البدائللا يوجد بديل لهذه الورقة.
Flat / Galvanised
Galvanized flat steel is manufactured by zinc-coating both sides of cold rolled metal by hot-dipping process. After having coated the steel surface with zinc, the coating of the interface is transformed into an alloy of iron-zinc layer through heating by induction and the galvannealed steel is produced.
